24. ssage Flashed messages flash at a fixed rate of approximately 3 times per second for a period of time assignable in two second intervals from 2 to 198 seconds or alternately until the next message is called up through the parallel input port Scrolled Message Scrolled messages scroll across the display from right to left at a fixed rate for a number of times assignable between 1 and 99 times or continually scroll until the next message is called up through the parallel input port Scrolling is especially useful in combination with chaining messages together to create continuous messages of up to 180 characters in length 2 2 Chaining Messages Together Any message can be the start of a chain that links together up to 8 additional messages Chaining is especially useful to create messages longer than 20 characters up to 180 character messages are possible with chaining These longer messages can be displayed either by scrolling the entire message or by alternately displaying lines Chaining is also useful in applications where a common message segment is defined in one message location and then repeatedly linked to other messages the overall effect being to reduce the amount of message memory used Each message can have its own independent chaining sequence defined thus 250 independent chains are possible one for each message For example messages 1 2 and 9 can have the following chained sequences defined all at the same time MESSAGE 0
25. trobe Or No Strobe Operation Although a strobe input is provided as part of the RUN port for some applications it is not necessary to use the strobe when calling up messages from the PLC These are applications where variable data will not be used and where the PLC outputs are guaranteed to stably change states within the display input debounce time of 5 milliseconds In such applications it is possible to permanently tie the strobe to the active position so in effect the display will be in a constant strobe mode and will take in whatever message number is present at the RUN port for at least 10 milliseconds The advantages of not using the strobe are easier programming of the PLC and requiring one less output to operate the display 4 7 Calling Up Messages Messages are called up through the RUN input port by simply loading the address in binary where input D7 1s the MSB most significant bit and input DO is the LSB least significant bit Some examples of message callups are listed in the table below D1 e o c a oO X c wo g N e o INPUT D7 BINARY VALUE 128 NO MESSAGE 0 0 MESSAGE 1 MESSAGE 2 MESSAGE 3 MESSAGE 27 MESSAGE 250 NO MESSAGE 251 NO MESSAGE 255 o R 9 DN zx o 2 200000 0000 0 OOOO OOOO O O O O OOOJA a 2 O ON A O w A O oue O ox 0000 Note In the above chart I refers to the active or on I O state For sourc
